Para desarrollar sistemas de software en Python, normalmente escribes archivos de texto que contienen el código fuente de Python. Puedes hacerlo con cualquier editor de texto, incluidos los que enumeramos en "Entornos de desarrollo de Python". Luego procesas los archivos fuente con el compilador y el intérprete de Python. Puedes hacerlo directamente, dentro de un entorno de desarrollo integrado (IDE), o mediante otro programa que incorpore Python. El intérprete de Python también te permite ejecutar código Python de forma interactiva, al igual que los IDE.
El Programa python
El programa intérprete de Python se ejecuta como python (se llama python.exe en Windows). El programa incluye tanto el propio intérprete como el compilador de Python, que se invoca implícitamente según sea necesario en los módulos importados. Dependiendo de tu sistema, puede que el programa tenga que estar en un directorio que figure en tu variable de entorno PATH. Alternativamente, como con cualquier otro programa, puedes proporcionar su nombre de ruta completo en un símbolo del sistema (shell) o en el script del shell (o acceso directo, etc.) que lo ejecuta.1
En Windows, pulsa la tecla Windows y empieza a escribir python. Aparecerá "Python 3.x" (la versión de línea de comandos), junto con otras opciones, como "IDLE" (la GUI de Python).
